In this paper, we discussed interlayer excitons in a \(\mathrm {WSe}_{2}/\mathrm {WS}_{2}\) –based van der Waals
heterostructure, for which recent experimental measurements of the polarizability through pump–probe
experiments [1]} have been performed. In these experiments,
the transition from bright to dark states has been accessed for both
interlayer and intralayer excitons. In this paper, we focused ourselves
solely on the transitions between intra–excitonic states for interlayer excitons in a circular \(\mathrm {WSe}_{2}/\mathrm {WS}_{2}\)  dot.
